Thanks very much, I will consider the mapping format by read
iocsr[0x420][49] like this:
static uint64_t map_format(void)

Do you need to recompute the entire interrupt map

Do you need to recompute the entire interrupt map when ipmap changes?
Sorry, could you

"cpu package" works ok as a device on the board.
I don't know if it's possible to have the iocsr address space controlled by the device,
especially since

I see you're putting control of this register into loongarch_qemu_read in

Thanks very much, I will consider the mapping format by read iocsr[0x420][49]
